13 Claims.

This inventionrelates to industrial trucks, and more especially toattachments therefor for receiving and raising a load upon a carriageand for tilting the carriage to any desired position to facilitate thedepositing of the load in any desired position and location to one sideof the longitudinal axis of the truck.

The primary object of this invention is to provide a carriage platformhaving means for attaching the same to an industrial truck of a typehaving a relatively short wheel base with a power unit at one end and aload handling mechanism at the opposite end. The load handlingmechani'sm usually comprises a vertically extendingupright of atelescopic type having a pair of load engaging lift arms mounted forvertical movement onthe upright. The upright is usually pivoted adjacentits lower endto enable the lift arms to be tilted forwardly andrearwardly.

The platform of the present invention is oscillatably connected to oneof the load engaginglift arms mounted on the upright and hydraulic meansare provided for pivoting the carriage platform on one of the loadengaging lift arms so the carriage platform of the present invention maybe moved from a horizontal to a vertical position, as desired, fordepositing the load on the platform to one side of the path of travel ofthe industrial truck.

It is another object of this invention to provide, in combination withan industrial truck of the type described, said industrial truck havinga vertically movable frame attached thereto, a pair of hydraulicallyoperated squeeze arms projecting forwardly from the vertically movableframe, said arms being movable inwardly and outwardly with respect toeach other. A sub stantially rectangular platform is provided having atubular member secured to its lower surface and disposed near oneendthereof. The tubular member extends forwardly and rearwardly withrespect to the industrial truck and a second tubular member is removablysecured to the lower surface of the platform near its other end 7 of thetubular members may oscillate on the-other of the squeeze arms andwhereby, upon the hydraulically' movable arms'being moved apart-fromeach other, the platform will be tilted about one of the arms by virtueof the tie rod'pulli'ng one end of the platform downwardly as thedistance between the movable arms increases, thus raising the other endof the platform' It is another objectof this invention to pro vide aplatform of the type described having means for tilting the platformaround the axis of one of thehydraulically movable arms and to providea'member or plate at the end of the platform remote from the pivoted endof the platform and projecting upwardly therefrom when the platform isin lowered position, and to the upper end of which the lower end of asecond plate is hingedly secured and to provide nydraulica-lly operatedmeans which is connected to the upper plate for pivoting the upper platerelative to the lower plate; The upper plate also has a pair or. armsextending inwardly therefrom towards the: other end of the platform,normally in parallel relation thereto, one of the arm's'being movableforwardly and rearwardly relative to the industrial truck and beingconnected to amovable piston rod which extends from a liy} drauliccylinder fixed to the upper or hinged plate.

Thus, the upper plate may be pivoted out of the way of any loadthat maybe placed on the plat form prior to its being raised and then the upperplate may be moved to its normal position parallel to the lower plate sothat the arms extending from the upper plate may straddle the load onthe platform and the movable arm may be moved towards the fixed arm for.clamping the load therebetween sothat, as the platform is tilted aboutone of the hydraulically movable and for-'- wardly projecting arms, theload will be held be-, tween the said arms projecting from the upperplate until the load ispositioned to one side of the path of travel ofthe truck, after which the pressure of the arms on the load may bereleased and the entire platform moved away from engagement with theload.

It is a further object of the invention to provide a new and improvedindustrial truck arrangement having a load handling mechanism mounted onone end thereof which includes a load elevating platform and means forchanging the atttitude of the platform from horizontal to vertical andvice versa and other means on the elevating platform adaptedtoolampingly engage the load to be carried by the" elevating platformform may be tilted to permit the grasping means to engage and grasp anobject disposed in off-set relation to the normal path of travel of theindustrial truck and then upon tilting the platform from a vertical to ahorizontal position, the object will be moved, with the platform, into aposition in line with the normal path of travel of the industrial truckthus permitting removal of the'said object from its row without thenecessity of positioning the industrial truck at an angle and withoutthe necessity of removing objects disposed either side of the selectedobject, which will thus permit the storing of objects in relativelynarrower rows than has heretofore been practicable to thus greatlyincrease the storage capacity of a given area, such as the floor of acotton warehouse. uSome of the objects of the invention having beenstated, other objects will appear as the description proceeds, whentaken in connection with the accompanying drawings, in which Figure l isa side elevation of an industrial truck and showing one form of theinvention applied thereto; Figure 2 is a top plan shown'in Figure 1; IFigure 3 is an enlarged elevation with parts insection and is takenalong the line 33 in Figure 2 and shows the manner in which the improvedcarriage platform is connected to one of the hydraulically operableswingable squeeze arms; Figure 4 is an enlarged front elevation showingthe. carriage platform mounted on the swingable squeeze arm and is takenlooking along the line 4-4 in Figure 1; V

Referring more specifically to the drawings, the numeral 20 broadlydesignate an industrial truck such as is shown in U. S. patents numbered2,287,007 and 2,428,223 issued to D. V. Johnson. The chassis of the lifttruck generally comprises a pair of side panels 22 joined at the topunder the feet of an operator by a transversely extending frame member23 which also serves as a floor board and joined at the rear by averticall extending partially cylindrical end wall 2'1. At the forwardend of the vehicle each of the side panels 22 is provided with atransversely extending partially cylindrical curved wall 25 which isspaced slightly apart from eachof the front wheels 26 to form a fender,and the wall 25 is joined to a forwardly extending supporting flange 21(Figures 1 and 5) which is secured to a front axle housing 28.

The front wheels 25 are mounted on conven tional axles, not shown,within the axle housing 28 and which are driven by conventional gearingdisposed within a transmission housin 3! (Figure 5). The referencecharacter 33 indicates diagrammatically in Figure l the power unit whichis connected to the transmission housing 3 l. The chassis also has arear steerable wheel 59.

The chassis supports at its rear top a circular member 52 (Figures 1 and2) which supports a forwardly extending arm 53 which houses-the steeringmechanism and carries a seat 59 for the driver or operator of thevehicle and supports at its forward end a steerin wheel 55 which directsthe steerable wheel 50.

The numeral 60 indicates diagrammatically in Figure 2 a reservoir orexpansion tank which is supported by the chassis of the truck 29. Thisexpansion tank 60 is also shown schematically in Figure '7 and has asuitable hydraulic gear pump 61 mounted therein which is driven by thepower unit 33 in a conventional manner. The expansion tank 69 in Figure'7 has a suitable hydraulic fluid 10 therein in which one end of anintake pipe H is submerged, the other end of the pipe leading to thehydraulic pump 8 I. 7. The expansion tank 60 also has a discharge pipe12 extending from the same which also extends from the pump 5! and areturn pipe 13 also extends from the tank 58. The pipes 12 and 13 areconnected at their other ends to manifolds l4 and 15, respectively(Figures 2 and '7). Referring to Figure 7 it may be observed that themanifold 14 has supply pipes 11 to 8| inclusive extending therefrom, andthe manifold has return pipes 81 to SI, inclusive, extending therefrom.The

pipes" to 8|, inclusive, and 81 to SI, inclusive, are omitted fromFigures 1, 2 and 5 for Purposes -of clarity, inasmuch as they would haveto be nected to the valves '91 to NH, inclusive, respectively, as shownin Figure 7. The valves 81 to IDI, inclusive, are to be later describedand these valves are also shown in Figure 2 diagrammatically.

The valves 91 to IBI, inclusive, have control levers I01 to III,inclusive, respectively, extend- 'ing upwardly therefrom, there beingsuitable openings I I2 and I It in the upper horizontal portions'of theside panel 22 which are loosely penetrated by the control levers I61 toI I I, inclusive. It will be noted that these control levers arepositioned closely adjacent the seat 54 so that they may be easilyaccessible to the operator of the industrial truck.

Although the valves 91 to IUI, inclusive, are shown in Figure 7 as beingrotary valves, this showing is made merely by way of illustration so asto clearly define the manner in which the various cylinders and theipistons are operated.

There is shown in Figure 1 a suitable link H5 which is adapted to beconnected to a plunger II6, each of the valves 91 to II]! beingidentical but only the valve 91 being shown in Figure 1. This link II5has pivotally connected thereto at its upper end a bell crank arm H1 andthus by moving the levers I01 to III, inclusive, forwardly andrearwardly, the valve members 91 to IM are opened and closed. The valves91 to I-IlI are suitably secured to the chassis of the truck 26.

The control levers III] and III and their associated valves I66 and IBI,along with the expansion tank and the pump 6| are a usual part ofindustrial trucks of this type, as is clearly shown in the said PatentNumber 2,428,223 and a further description of the hydraulic systemassociated with this truck and with the present invention'will be givenlater in this specification.

Referring to Figures 1, 2 and 5, the front of the vehicle is providedwith an extensible telescopic elevator frame provided with a loadcarrying carriage, this assembly being broadly designated by thereference character I25.

The elevator frame comprises a pair of vertical frame sections mountedto telescope with respect to each other, the lower frame section beingindicated at I26 and the upper frame section or extensible frame beinindicated by the reference character I21. The extensible frame sectionI21 is mounted for up and down movement within the lower frame sectionI26. The upper portion of the lower frame I26 serves as an anchor forone end of a sprocket chain I31 suitably secured thereto.

At its lower end the vertical frame I26 is usually provided with a pairof rearwardly extending arms I46 and MI, one of which is seen in Figurel and both of which may be observed in Figure 5. Each of these bars I40and MI may be pivotally mounted on a hanger I44 (Figure 1) supportedfrom the front axle housing 28 so the load supporting assembly I25 iscarried by the portions 226 and 22I front axle housing and is mountedfor :pivotal movement either on the axle housing or the hanger I44. Therearmost end of each of the arms I40 and I4! is pivotally connected asat M5 to the free lower end of the piston rod I46 of a piston which ismounted for vertical reciprocation in a cylinder I41 (Figure l). Onlyone of the cylinders and its associated piston I416 is shown in Figure1, but both of the pistons and the cylinders I46 and I4! are shown inthe schematic diagram in Figure '7. Each of the cylinders I41 has a pipeI56 extending therefrom (Figure '7) which are coupled together thusforming a single pipe I5I which extends to one side of the control valveIOI.

The cylinder I41 is pivotally mounted on :the chassis as at I56 (Figurel) as is clearly shown in the said Patent Number 2,428,223. The cylinderI41 has a hydraulic piston, not shown, which is actuated by hydraulicfluid under pressure, as will be later described. in detail, to effect atilting of the frame I25 backward or forward at its upper end tofacilitate loading and unloading of the platformcarriage to 'be laterdescribed.

The frame I25 is moved in a clockwise direction in Figure 1 by thepiston I46 and is moved in a counterclockwise direction b gravity, sinceit is pivotally mounted at 43 to the right of its center of gravity.Industrial trucks of this type are also usually provided with means toassure the return of the tilting assembly 'to a vertical position whenit has been tilted forwardly and to assure the emptying of the hydraulicfluid from the cylinders I41 when hydraulic pressure isiremoved, all ofWhich is clearly shown in said Patent Number 2,428,223. A. piston I63 ismounted for vertical sliding movement in a cylinder I62 for actuating orlifting the upper frame section I21. The cylinder IE2 is supported bythe lower frame section I26.

The upper end of the piston I63 (Figure '5) engages the lower end of aU-shaped bracket :I'Hl having a belt I1I penetrating the same on which asuitable pulley I12 is rotatably mounted. The

upper end of the U-shaped member is welded'to the extensible framesection I21.

The upper movable frame section I21 supports a vertically movablesubstantially rectangular framework broadly designated at I (Figure '6)This rectangular frame I65 i guided on the .upper movable frame I21 by aplurality of rollers I86 to I93, inclusive, the rollers I86 to I89inclusive not being visible in Figure 6, but all of the rollers beingshown in Figure 10.

The rollers I86 to I23 engage the vertically movable frame I21 so as toguide the rectangular frame I85 in a plane parallel to the verticalframe I21 and to prevent tilting of the rectangular frame I65independently of the vertically movable frame I21.

The modified form of the invention shown in Figures 10 to 14, inclusive,is mounted on lift arms which are usual parts of industrial trucks ofthis type and which are also shown in the said Patent Number 2,428,223.These arms, which. are designated at 2I6 and .2 I1, are pivotallymounted at their upper ends on a horizontally disposed shaft 295 carriedby the rectangular framework I85 and are provided with horizontallydisposed respectively, extending therefrom. These portions 22s and 22Iare usually tapered toward their outer ends on their lower sides, sothat the tapered sides :may extend parallel to the floor or ground whenthe frames I26 and I21 are tilted forwardly to take on a load.

The chain I31, which has heretofore been described as being secured tothe upper end of the lower frame I26 (Figures 1 and 2), passes over thepulley I12 mounted in the upper end of the extensible frame I21 andpasses down parallel to the piston I63 and the cylinder I62 and has itsother end suitably anchored to the upper end of the rectangular frame I85 It should be noted that when the piston I63 is forced upwardly byhydraulic fluid under pressure in the cylinder I62, it engages themovable frame section I21 (Figure 5) and lifts the upper frame sectionI21 as well as the pulley I12. Since the rear end of the chain I31 isanchored to the lower frame section I26, the raising of the pulleyextends both the forward and rearward bight or reach of the chain I31and the rectangular frame I85 is raised twice as fast as the upper orvertically movable frame section I21.

Since the piston I63 and cylinder I62 perform as a single actingcylinder and the piston 63 is returned in the cylinder I62 by gravity,there is but single pipe 221 which extends from the lower end of thecylinder I62 and is connected at ed on the rectangular frame I85, in amanner to be later described.

It is to be understood that the structure of the auxiliary frame 235with its hydraulically actuated arms is not considered a part of thepresent invention with the exception of its combination with the presentinvention. However, a substantial description of the same follows sincethere 5 are no known existing patents to which reference may be made fora complete description of the same.

Referring to Figures 1, 2, l, 5 and 6, it may be observed that the arms2I6 and EH shown in Figure 10 are removed from the horizontally disposedshaft 295 and an inverted horizontally disposed channel bar 236 of theauxiliary frame 235 bears against the front surface of the rectangularframe I85 and has a pair of spaced ears or bosses 231 thereon which areadapted to be slidably penetrated by the shaft 205 to thus connect thechannel bar 236 to the rectangular frame I85. There are various ways inwhich the auxiliary frame 235 may be secured to the rectangular frameI85, the methods shown being by way of illustration only.

Pivotally connected between the flanges of the channel bar 236, as at253 and 254, are depending swingable arms 255 and 256, respectively.These arms 255 and 256 are shown as being circular in cross section andhave forwardly extending gripper or squeeze arms 251 and 258,respectively, secured thereto as by welding. The squeeze arms 251 and258 are also preferably circular in cross section and are rounded attheir front ends at 266 (Figure 6). The rounded front ends 266 of thesqueeze arms 251 and 258 are provided to assist in guiding the members251 and 258 as'they are moved into tubular members,

i 8 to be later described, associated with the improved carriageplatform.

Referring to Figures 4 and in may be ob served that the upper ends ofcylinders 263 and 264 of the double actin type are pivotally connectedas at 265 and 266, respectively, to the flanges of the horizontallydisposed channel bar 236. The cylinder 263 ha flexible pipes or hose 210and 2H extending therefrom and the cylinder 264 has flexible pipes orhose 213 and 212 extending therefrom.

It will be noted in Figure 7 that the flexible pipes 212 and 213 areconnected to the flexible pipes 210 and 21I and these pipes 210 and 2",in turn, extend to separate ports in the valve 99.

The structure of the double acting cylinders 263 and 264 as well as anyother double acting cylinders associated with this apparatus may beidentical and therefore only the structure of the cylinder 263 will bedescribed. Referring to Figure 16, it may be observed that the cylinder263 has a suitable piston broadly designated at 215 mounted therein forlongitudinal sliding movement. This piston 215 may be of any desiredstructure and has a piston rod 216 connected thereto.

The cylinder 263 is provided with a port 286 at one end which isthreaded for reception of a suitable pipe fitting, 281 to one end ofwhich one end of the pipe 216 is connected.

Secured, as by welding to the right-hand endof the cylinder 263 inFigure 16 is a cap member 290 having a port 29I which is threaded forreception of the pipe fitting 293, to the outer end of which the pipe21! is suitably'connected.

Referring again to Figure 4, the cylinder 264 has a piston rod 295extendin therefrom which is identical to the piston rod 216 extendingfrom the cylinder 263. The piston rods 216 and 295 are pivotallyconnected at their free ends, as at 296 and 291, to the proximate sidesof the pivoted arms 255 and 256.

This completes the description of the squeeze arm attachment, comprisingthe auxiliary frame 235 and its squeeze arms 251 and 258, as it isusually used and in which instance the arms 251 and 258 straddle theobject, which is usually a resilient object, such as a bale of cotton.The squeeze arms are moved inwardly by moving the upper end of thecontrol lever I99 in Figure 2 rearwardly so as to cause the fluid underpressure to flow from the pump 6| through pipe 12, valve 14 and pipe 19through a passageway 393 in the core 99a of the valve 99, since thisvalve core 99a has been rotated a quarter revolution from the positionshown in Figure '7, and thus through the pipes 2H and 213 to the lowerends of the cylinders 263 and 264 to thus cause the piston rods 216 and295 to be drawn into th cylinders 263 and 264, in which instance thefluid would return through the pipes 210 and 212 and through apassageway 304 in the valve 99 and through pipe 89 to the manifold 15and then through the return pipe 13 into the expansion tank 69. Thevalve 99, of course, would be rotated 90 degrees from the position shownin Figure 7 during this period.

Now, when it is desired to release the object from between the squeezearms 251 and 258, the control lever I09 is moved forwardly at its upperend to thus rotate the valve core 99a from its prior position to theposition shown in Figure 7 to thus cause the fluid to flow to the upperends of the cylinders 263 and 264. This will, of course, project thecorresponding piston rods 216 and 319 295 outwardly to move the squeezearms 25'! and 258 apart from each other and the fluid will return fromthe lower ends of the cylinders 263 and 264 to the expansion tank 65.

Now, referring to Figure 7, and assuming that the operator desires totilt the upper ends of the frames :23 and $21 baokwardly or to the rightin Figure l, the lever i i l is moved rearwardly to thus position a coreMia of the valve It! in the position shown in Figure '7 with the resultthat the fluid under pressure will flow from the pump through pipe 12,manifold 14, and pipe 8i.

to the valve lfil. The valve core 555a has a passageway 305 extendingtherethrough, throughwhich fluid will pass into the pipe iiii and theninto the pipes 55! to force the pistons 145 downwardly in Figures 1 and7 to thus cause the frames H5 and 521 to move in a clockwise directionin Figure l.

The core 555a. of the valve 131 in Figure 7 also has a passageway 33%and when the lever H5 in Figure 2 is moved forwardly at its upper end,the core 1cm in Figure 'i is rotated 90 degrees in a clockwise directionfrom the position shown in Figure 7. The weight of the frames H5 and i2?and associated parts will then cause the pistons I58 to move upwardly inthe cylinders I31, resulting in the fluid returning through the pipesI50 and -15! to the valve 13!. The fluid will then return to theexpansion tank 60.

raise the frame 121 and the associated rectangular frame I85 along withthe framework 235 and its squeeze arms 251 and -258, the control leverH5 is moved rearwardly to thus position the core 133a of the valve I09as shown in Fig-v ure 7. The fluid will then flow from the expansiontank 5!! to the valve tell. has a passageway 3! extending therethroughand another transverse passageway 3H'coine municating therewith andextending to the out.-

side of the valve core 138a and fluid will then flow under pressure fromthe pipe 30 through the passageways 3H] andSH, successively, and thenthrough the pipe 221 to the lower end of the cylinder I62. This will,oi' course, cause the iston 163 to move upwardly to raise the frame I21and the rectangular frame I85, in the man ner heretofore described,after which the con- I trol lever H5 may be released and the core [Marwill rotate about 45 degrees to thus move bothof the passageways 3H3 and31 I out of alinement with the pipes 221, 95 and 83. Now, when it isdesired to again lower the rectangular frame 185,

the control lever H9 (Figure 2) is then moved forwardly at its upperfree end to thus move the core 135a in the valve H15 (Figure '7) 90degreesin a counterclockwise direction from that shown in Figure '7.This will, of course, aline the pas-- sageway 358 with the pipes 221 and9.3, as a Improved carriage platform Figures 1 to 5, inclusive, show thestructural details of the improved carriage platform which is broadlydesignated at 315. This carriage platform is adapted to be mounted onthe squeeze arms 25! and 258 andm-ay be easily removed Now, assumingthat the operator desires to The core 4 53a- 1 0 therefrom when it isdesired'to use the squeeze arms 25.1 and 258 for-other purposes asheretofore disclosed. The means for mounting the improvedcarriageplatform 3l5 on-thesqueeze. arms 25] and 258 will be laterdescribed.

The carriage platform 315 comprises a rectangular plate 316, Which, forpurposes of de! scription, we will assume is in a horizontal po-.

sition as-show-n in Figures 1, 2, 4- and 6, although it isto beunderstood that this plate 315 may be tilted to assume any desiredattitude, as will be.

later described, from horizontal to vertical.

' This plate M3 has extending along its front edge and projectingdownwardly therefrom, andbeing welded thereto, a reinforcing plate 3Hhaving leg portions 325 and 32i-at opposite ends.

thereof for supporting the front end of the-platform 315 when itisrestingon the floor or ground independently ofthe squeeze arms 25! and258.v

Welded to the top rearedge of the plate 3l6 is another reinforcing-bar322.

Referring to Figures 4 and 5 it may be ob:

served that there a tubular member, such as a pipe 325, welded to thelower surface of the plate 316. This pipe 325 is positioned asubstantial distance from the left-hand end of the plate 315 as observedin Figure 4 and extends a short distance beyond the rear edge of theplate 316. and has an annular member v 32 6 fixedly secured.

thereon as by a pressed fit or by welding.

The annular member 323 is provided with a peripheral groove 321 "(Figure3) for purposes tov be later described.

Welded to the lower surface of the plate 3Hi adjacent its left-hand rearcorner in Figure 4 is a depending plate 330 the lower end of whichterminates in a horizontal plane slightly above that of the leg portion.321 of the reinforcing plate 311. Pivotally connected to the plate 33.0as at-33l is one end of a connectingrod 332 which is threadabl-y mountedat its other end .in:

Referring to Figures '1- and 5, it may be observed thatthe pipe 331 hasa block 338 welded to its upper surface in substantially verticalalinement with the arm 336. and the upper surface of this block 338normally supports the... plate (H6. The plate 3l6 has a .slot .340therein.v

which is loosely penetrated by the threadedpor: tion of a thumb screw34.! when the plate. :316 is locked in engagementwiththepipe 331. Whenthe thumb screw 34.! is turned at. right angles.

from the position shown in Figure 2, then the slot 3% permits the lower.end of the plate, 3 It .in-

Figure Zto-be moved away fromthe .pipe 3.31.

by means to be later described. Referring to-Figures 1 and 2 it may beob:

served that the right-hand endof the. tubular.

member 331 has a dog clutch member 34.3..fixedly mounted thereon as bywelding. Now, whenthe; squeeze arms 251 and 2.58. are slid into. the;

tubular'members 325 :and 331, the .dog clutch member 343 is adapted toengage a fixed dogs;

clutch member 344weldedto the .pivotedarm 255 and thesqueeze arm 25] tothus prevent-rota. tion of the tubular member 331 on the squeezearm 251.The squeeze arm 25.1 maybe pro;- vided with a transverse bore 34.5(Figurenfi).

adapted to be loosely penetrated -.by a spin 346 (Figure 1) to furtherassist in locking the member 331 on the squeeze arm 251 if desired.

When the squeeze arm 258 is inserted in the tubular member 325 theright-hand end of the tubular member 326 in Figure 3 will engage a plate358 which is secured as by welding to the lower portion of the pivotedarm 256. This plate 358 extends upwardly from the squeeze arm 258, whichalso penetrates the same at its connection with the pivoted arm 256, andhas a guide block 35I secured thereon as by screws 352.

The guide block 35] is slidably penetrated by an upwardly projecting arm353 having a semicircular locking member 354 integral therewith andwhich is adapted to engage the peripheral groove 321 in the annularmember 326 as shown in Figure 3 to thus prevent the member 325 fromsliding 01f of the squeeze arm 2.58 unintentionally but still permittingrotation of the member 325 on the squeeze arm 258. The arm 353 has a pin355 projecting therefrom which is adapted to engage the upper edge ofthe guide block 35I when the tubular member 325 and its associated plate3I6 of the carriage platform 3I5 are removed from the squeeze arm 258.

Welded to the right-hand end of the plate 3I6 in Figure 4 and projectingupwardly therefrom is a vertically disposed end plate 368 which hashingedly connected to its upper end, as at 361, a swingable plate 362.The plates 368 and 362 extend forwardly and rearwardly from the front tothe rear of the plate 3I6 and may be reinforced throughout their lengthin any desired manner. It will be noted in Figure 6 that the hingeportion 36I extends the full length of the members 368 and 362.

The plate 362 has a pair of ears 363 projecting outwardly therefrombetween which the upper end of a piston rod 364 has oscillatorymovement. The upper end of piston rod 364 is pivotally connected asat365 to the ears 363. The piston rod 364 has vertical sliding movement ina double acting cylinder 366 which is identical with the double actingcylinder 263 heretofore described and a further description of the sameis deemed unnecessary, This double acting cylinder 366 has flexiblepipes or hose 361 and 368 extending therefrom and being connected attheir other ends to separate ports in the valve I 98 (Figure 1).

Itv will be noted in Figure 7 that the valve 98 has the partiallyrotatable core 98a having curved passageways 3H and 312 therein whichare positioned substantially as shown in Figure '1 when the controllever I88 is moved forwardly (Figures 1 and 2) and in. which instance,the hydraulic fluid under pressure would flow from the hydraulic pump 6|through pipe 12, manifold 14 and pipe 18 to .the valve 98. The fluidwould then flow through the passageway 31I and pipe 361 to the upper endof the cylinder 366 to thus cause the piston rod 364 to move downwardlyand to move the hinged plate 362 in a clockwise direction in Figure 4substantially as shown in Figures 11 and 12. The plate 362 may bestopped in any desired attitude within 90 degrees of that in which it isshown in Figure 4 if desired by moving the control handle I86 to itsnormal vertical position. In this instance the core 98a in valve 98(Figure '1) would be rotated approximately 45 degrees to where thepassageways 31I and 312 would not be in alinement with any of theassociated pipes.

On the other hand, when it is desired to return the plate 362 from theposition shown in Figures 11 and 12 to that shown in Figure 4, thecontrol lever I88 would be moved rearwardly to thus partially rotate thecore 98a in Figure 7 to where the passageway 31I would connect pipes 18and 368 and the passageway 312 would connect pipes 88 and 361. Thus,fluid under pressure would flow through the pipe 18, passageway 21I andpipe 368 to the lower end of the cylinder 366 to thus move the pistonrod upwardly, the fluid returning through the pipe 361, the passageway312 in the core 98a and the pipe 88 to manifold 15 from which the fluidwould return to the expansion tank 68 through the pipe 13.

Thehinged plate 362 has an elongated slot 315 therein which is adaptedto be loosely penetrated by a forwardly and rearwardly movable squeezearm 316 (Figures 1 and 4). This movable squeeze arm 316 is similar to afixed squeeze arm 311 the lower end in Figure 2 of which is secured asby welding to the right-hand end of the hinged plate 362. The movablesqueeze arm 316 has an enlarged guide block portion 388 integraltherewith which is slidably penetrated by spaced guide rods 38I and 382secured as by screws 383 (Figure 1) to blocks 384 and 385 welded to andprojecting outwardly from the hinged plate 362.

It will be noted that the right-hand block 385 is substantially widerthan the left-hand block 384 in Figures 1, 5 and 6 and has securedthereto, as by a bolt 398, one end of a double acting cylinder Billwhich is identical to the double acting cylinder 263 heretoforedescribed. The piston rod 392 of the cylinder 39I has a restrictedthreaded portion at its left-hand end in Figure 1 which slidablypenetrates the block portion 388 of the movable squeeze arm 316 and thisblock portion 388 is secured thereon as by a nut 394. The cylinder 39Ihas pipes 396 and 391 extending from opposite ends thereof which areconnected at their other ends to separate ports of the valve 91 and itwill be noted that the valve 91 has the partially rotatable core 91atherein having curved pasp sageways 488 and 48I therein.

Now, by moving the free end of the control lever I81 rearwardly, thecore 91a is positioned as shown in Figure 7 so that hydraulic fluid willflow from the pump 6| through pipe 12, manifold 14, pipe 11 and thepassageway 488 in valve 91, through pipe 396 to the right-hand end ofthe cylinder 39I t0 thus move the piston rod outwardly and to move themovable arm 316 away from the arm 311. Fluid will return through thepipe 391, through the passageway 48I in valve 91, through the pipe 81,manifold 15, and finally through the pipe 13 to be discharged into theexpansion tank 68.

When it, is desired to move the squeeze arm 316 toward the fixed arm 311for squeezing or clamping an object therebetween, the lever I81 is movedforwardly to thus turn the core 91 a ninety degrees to the positionshown in Figure 7. Fluid under pressure will then flow to the pipe 11 inthe manner heretofore described and then through the passageway 488 inthe valve 81 and through the pipe 391 to the left-hand end of thecylinder 39I to thus move the piston rod from left to right in Figures1, 3 and 7, and to move the arm 316 correspondingly. The fluid, ofcourse, will return through the pipe 396 and the passageway 48l in valve91 and through pipe 81 to the manifold 15 and thus through the pipe 13to be discharged into the expansion tank 68.

Referring to Figures 5, 8 and 9 there may be observed tiered bales ofcotton C which are representative of the many objects which may behandled with this apparatus and these tiered bales of cotton C areusually arranged in warehouses and the like in closely spaced parallelrows, the bales of cotton C in an adjacent row being shown in Figureonly.

It is a well known fact that objects stored in warehouses andparticularly bales of cotton, are owned by many separate and distinctparties and many instances there are many various qualities or grades ofcotton or the like which may be in bales immediately adjacent eachother.

Heretofore, in order to remove a particular article from the middle ofany given row of articles, for instance, it has been necessary to spacethese rows sufliciently apart from each other to permit industrialtrucks, such as that shown in Figure 1 withoutthe improved carriage 3 l5 thereon, to be turned crosswise of the aisle formed by the rows oftiered articles. This, of course, caused a considerable waste ofvaluable storage space due to larger aisles, and this also savesconsiderable wear on the truck and saves time in manipulation of thetruck. In the present invention, and as is clearly shown in Figures 5, Band 9, the space between adjacent rows of tiered articles or objectsneed only be slightly larger than that of the width of the truck orsufficient for the width of the improved carriage platform 3l5 to passtherebetween.

When the industrial truck 25 has been moved toa position adjacent thedesired bale of cotton or the like, it is merely necessary for theoperator to move the free end of the control lever I95 forwardly to thusdirect fluid under pressure to the upper ends of the cylinders 263 and264 in the manner heretofore described, which, of course, will result inthe piston rods 216 and 295, respectively, moving the squeeze arms 25'!and 25% away from each other. This will cause the platform M5 to betilted as shown in Figure 5 due to the fact that the tubular member 325is oscillatably mounted on the arm 258 while the tubular member 331 isfixed on the squeeze arm 25] and thus the squeeze arm 25'! will move theright-hand end of the connecting rod 334 to the right thus moving theplate 3I6 in a counter-clockwise direction as the arms 25'! and 258 moveapart from each other.

The squeeze arms 316 and 311 on the hinged plate 362 will straddle thedesired bale of cotton and then fluid under pressure will be admitted tothe left-hand end of the cylinder 33I in Figure 1 thus causing thesqueeze arm 316 to engage the bale of cotton and squeeze the bale ofcotton between the arms 316 and 311. After this, fluid under pressuremay be admitted to the lower ends of the cylinders 263 and 264, in themanner heretofore described, by moving the control lever E09 rearwardlyto thus cause the squeeze'arms 257 and 258 to be moved inwardly towardseach other until they assume the position shown in Figure 4.

Figure 8 shows the platform 3l5 in the position that it will assume whenthe squeeze arms 257 and 258 are moved inwardly towards each other arelatively short distance from the position shown in Figure 5 and Figure9 shows the position of the platform 3H5 when the squeeze arms 25! and255 have been moved to their innermost position. It is seen that uponthe upper bale of cotton being moved inwardly as shown in Figure 5 andfinally to a vertical position similar to that shown in Figure 9, thecontrol levers H0 and Ill may be moved rearwardly to a veri4 ticaiposition, successively, to thus lower the: platform 3l5 to the positionshown in Figure 9 after which the lever I01 may be moved forwardly tomove the squeeze arms out of engage ment with the bale of cotton andthen the lever [25 may be moved forwardly at its upper free end totilt'the hinged plate 362 and its associated arms 3'53 and 311 out of the wayof the bale of cotton C so that another operatormay pull the bale ofcotton C onto a suitable hand truck or the like. It is obvious that theapparatus may be used in removing the lower bale of cotton shown at theleft-hand side of Figures 5, 8 and 9 in a like manner to that in whichthe upper bale of cotton is removed.

Modified form of the invention Referring to Figures 10 to 15, inclusive,there is shown a modified form of carriage platform broadly designatedat H5. This modified carriage platform 4I5 is very similar to theoriginal form of platform 3l5 and many of the parts are identical andtherefore the same reference characters will apply and where modifiedparts are used, a concise explanation will be given to define which partis replaced by the modified parts.

In the modified form of the invention, the tu-' bular member 325 whichis welded to the lower surface of the plate 3I3 and the tubular member 331 which supports the free end of the plate 3|5 when in a lowered orlevel position, are very similar to these same members 325 and 331 as-'sociated with the original form of the platform 3i5, with the exceptionthat the rear ends of the pipes 325 and 331 do not extend rearwardlybeyond the rear edge of the plate 3l6 (Figure 15) The platform H5 isparticularly adapted for use with truck lifts having the lift arms H6and 22? mounted on the rod 265 associated with the rectangular frame Iand which are used in lieu of the frame 335 and its associated squeeze.

arms 25? and 258. The dog clutch member 343 is also omitted from therear end of the pipe 331 and the annular portion 326 is also omittedfrom the end of the pipe 325 in the modified form of the invention.

Referring to Figure 10 it may be observed that the pipe 331 of theplatform 415 is provided with horizontally disposed plates M5 which arespaced apart from each other and extend longitudinally of the pipe 337and extend at their rear ends beyond the rear end of the pipe 331. Thehorizontal portion 220 of the lift arm H6 is adapted to slide into thespace between the horizontal plates M5 and a headed pin 425 slidablypenetrates the plates ilfi as well as the arm 22!] to thus lock the pipe331 in position on the arm 220.

Referring to Figure 15 it may be observed that,

the tubular member 325 of the modified platform M5 is welded orotherwise secured to the lower.

surface of the plate 3E5 and terminates a substantial distance from thefront and rear edges the tubular member 422 when the plate 3l6 of theplatform is tilted in a manner to be later described.

. Extending longitudinally of the tubular member 422 and also beyond therear end of the same in Figure 15 is a pair of spaced plates 425 betweenwhich the portion 22| of the lift arm 2H is adapted to be slidablyinserted. A suitable headed pin 42'! slidably penetrates the exposedrear ends of the plates 426 as well as the arm 22! to thus prevent thetubular member 422 as Well as the tubular member 325 and its associatedplate 3l6 from sliding off the horizontal portion 221 of the lift arm 2Hunintentionally.

- Inasmuch as the arms 2!! and 216 do not move apart from each other inthe same manner that the squeeze arms 251 and 258 move apart from eachother, but remain in a fixed vertical position, the tie rods 332 and 334along with the turn buckle 333 of the original platform 3!!) are omittedfrom the modified platform 415 and are replaced by a double actingcylinder 438 having a piston 43! mounted therein for longitudinalsliding movement and to which a piston rod 432 is connected. The doubleacting cylinder 430 and its associated piston 43| are identical to thecylinder 263 (Figure 16) and its associated piston 215 and a furtherdescription thereof is deemed unnecessary. Also, in view of the factthat the cylinders 263 and 264 are not employed in the modified form ofthe invention shown in Figure 10, the flexible pipes 270 and 2'" inFigure 7 are directed as shown in dotted lines to opposite ends of thecylinder 43!).

The right-hand end of the cylinder 430 in Figure 10 has outwardlyextending ears 435 integral therewith which are pivotally connected asat 436 to the plate 336 extending downwardly from the tubular member331. The piston rod 432 is pivotally connected at its free end as at 431to the lower end of the plate 330 which depends from the lower surfaceof the horizontally disposed plate 3 l 6.

By referring to Figures 11, 12 and 13, it may be observed how theattitude of the platform 4l5 may be changed from horizontal to verticalor vice versa due to the fact that the platform 415 oscillates about thetubular member 422 on the arm 22! while the pipe 33? remains in a fixedposition on the horizontal portion 220 of the lift arm 2l6. In order tomove the platform 415 about its axis, say from the position shown inFigures 10 and 13 to that shown in Figure 11, the lever 109 (Figure 2)is moved in such a manner as to cause fluid under pressure to flow fromthe pipe 19 (Figure 7) through the passageway 304 in valve 99 andthrough the pipe 210 to the left-hand end of the piston 433, thuscausing the piston rod 532 to move from left to right in Figure 10through the position shown in Figure 12 and to the position shown inFigure 11. It is manifest that by moving the lever H39 in the oppositedirection, fluid will be directed to the right-hand end of the cylinder43!? to thus move the piston rod from the position shown in Figure 11 tothat shown in Figure 10, thus moving the platform H5 from a vertical toa horizontal position. M

Referring to Figure 14 it may be observed that the arms 3'16 and 3'51are each provided with a removable curved member 443 both of which areidentical. These curved members 440 have elongated flattened portions44| integral therewith which are adapted to be slidably penetrated bythe arms 316 and 31'! and the members 443 are locked on the arms 316 asby set screws 442. It

is thus seen that these arcuate or curved members may be easily removedfrom the squeeze arms 316 and 311, when desired, and the purpose ofthese curved members 440 is to provide for the handling of circularobjects such as rolls of cloth, tar paper or the like, or cylindricalcontainers, such as oil drums.

Although the curved members 440 are shownassociated with the modifiedplatform 4l5 only, it is obvious that these arms 440 may also be usedequally as well with the original form of the platform 3l5. As seen inFigure 14, the curved members 440 curve inwardly towards each other whenthey are mounted on the squeezev arms 3'16 and 31"! and thus thecylindrical arti cle which is to be handled, and which is indicated at Bin Figures 11, 12, 13 and 14, may be placed on the platform 4i5 whilethe plate 362 is in a position perpendicular to the plate 360' and thenthe plate 362 may be moved into alinement with the plate 360, in themanner hereto-.

the hinged plate 352 may be turned at right angles to the plate 360 tothe position shown in Figures 11 and 12. Then the article B may beplaced atop a similar article B substantially as shown in Figures 12 and11.

It is thus seen that I have provided a tiltable platform for industrialtrucks which will handle articles that are of cubical, cylindrical orirregular shape and which will facilitate lifting the articles andpositioning them to one side of the normal path of travel of theindustrial truck. And it is seen that the articles may be positioned toone side of the truck in the same attitude that they were placed on theplatform or they may be turned on one side as desired.

In the drawings and specification there has been set forth a preferredembodiment of the invention, and although specific terms are employed,they are used in a generic and descriptive sense only, and not forpurposes of himtation, the scope of the invention being defined in theclaims.
